Bug Description
The system is an Acer TravelMate 212TVX laptop. The operating system version is Ubuntu 8.10 (first freshly installed,
with the original 2.6.27-7 kernel, and later auto-updated through wired network, with kernel 2.6.27-9).
If the Netgear WG511 (v1) wifi PCMCIA card is already inserted at bootup the system freezes completely around 16%
of bootup process (right after starting the sound card driver, as a small click can be heard through the speakers when
the sound card is started). While the system is completely locked (no keyboard, no console switching, nothing)
just by removing the wifi card the system responds at once and resumes the bootup process with no more
problems.
If the module is blacklisted (in /etc/modprobe.
with "sudo modprobe p54pci" the system freezes as well most times, but not always. When there is no lockup, usually
the card doesn't work at all, but I've seen it working 2 times (out of 20 or so). If the system freezes, removing the card
unlocks the system and everything is fine.
Tested the computer with a PCMCIA ethernet card and everything works fine, the system boots quick and smooth and
network connectivity under ubuntu GUI is perfect, so it seems that the PCMCIA port is not the source of the problem.
As usual, the wifi card works well under windows xp. Under prims54 the card works too, and doesn't freeze at all, but
this old module has a lot of problems with WPA, and WEP is not an option right now. I've seen in the module blacklist
file that prism54 has been deprecated by default in ubuntu 8.10 (because of the WPA problems, I suppose).
Tried to start the systema with acpi=off, noapic, nolapic and all that, just in case, but nothing changed. Updating the
kernel chaged nothing as well.
Best regards.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information.
Please include the following additional information:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after inserting and then removing the wifi card and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" with the wifi card inserted and attach the resulting file "lspci-vvnn.log" to this bug report.
